Article Abstract
Purpose: To detect the effect of active calcium ions solution on the ultrastructure of enamel and cementum of the extracted teeth and observe the cytotoxicity of the solution on NIH3T3 cell through cell culture.
Methods: Active calcium ions solution composition was detected with a Quanta200FEG field emission scanning electron microscopy, and the ultrastructure of teeth enamel and cementum was observed before and after the application of calcium ions solution. After diluting the calcium ions solution, MTT assay method was used to observe the impact of active calcium ions solution of different concentrations on the NIH3T3 cells growth. Based on cell relative growth rate, the cytotoxicity grade was rated.
Results: Active calcium ions solution was composed of calcium, carbon, oxygen, and chlorine. And there was no change in the enamel and cementum before and after soaking the teeth with active calcium ions solution. The maximum concentration of safe calcium ions solution on cytotoxicity grade was 0.344 mg/mL.
Conclusions: Active calcium ions solution can be used in the oral cavity,but appropriate concentration should be selected.

The primary objective of this review is to analyze primary research published over the past six years concerning cyclic nucleotide-gated calcium channels (CNGC) in plants. The aim is to structure this information to identify and organize existing knowledge regarding their tertiary and quaternary structures, as well as the activation mechanisms of CNGC. Studies on plant CNGC published between January 2018 and May 2025 were included, while research focused on animals, bacteria, or ions other than calcium was excluded.

Aim: Periodontitis is a common complication of type 2 diabetes. Imperatorin is a traditional Chinese medicinal compound recognized for its anti-inflammatory, analgesic and anti-tumor properties. Nevertheless, the impact of imperatorin on chronic periodontitis and chronic periodontitis associated with type 2 diabetes mellitus remains unexplored.

Multidimensional modulation of the bone marrow niche represents a pivotal therapeutic strategy for bone-related disorders. However, its clinical translation remains challenging due to the inherent limitations imposed by the bone physiological barrier. Herein, a bone cavity-targeted nanocomposite (ZCD) is developed that can respond to extracorporeal shock wave (ESW), enabling triaxial regulation by inhibiting adipogenic differentiation, promoting osteogenic differentiation, and suppressing osteoclast activity.

Hyperosmolality-triggered physiological drought hinders plant growth and development, leading to a drop in crop yields. Hyperosmolality triggers calcium signaling, and yet how osmotic-induced calcium signaling participates in cellular osmotic response remains enigmatic. To date, several Ca channels and transporters have been identified to regulate osmotic-induced calcium signal generation (CaSG) or Ca homeostasis.

Background: Colorectal cancer (CRC) is a highly prevalent and fatal malignancy worldwide. Despite advancements in early screening techniques and treatments, the prognosis for patients remains suboptimal. Studies have shown that metal ions play crucial roles in the occurrence, progression, and treatment of CRC.
